Engineering optical properties of quantum dot systems
Abstract
Properties and functions of nanodevices are determined by quantum behavior of nanosystems which constitute the nucleus of the nanodevices. This work is devoted to investigation of the linear and nonlinear optical properties of quantum dot systems, in part the intrinsic optical bistability. The resonance effects and many-body effects in the systems as well as the self-consistent treatment of the phenomena form the framework of the consideration. Effects of the size parameters of quantum dot systems, shapes of quantum dots, and electron population of quantum dots on the optical properties are investigated. It is shown that a few Angstroms more or less and/or one electron more or less can make a dramatic difference in the nanosystem behavior. Knowledge of the maps of the allowed dipole coupled interlevel transitions in quantum dots are demonstrated to be crucially important. A special attention is paid to the vital effects of the electron-electron interaction in the quantum dot systems: static, dynamic, intradot, and iterdot.
